BEER-COOLING APPARATUS.

SPECIFICATION formingpart of Letters Patent No. 276,870, dated May 1, 1888. Application filed February 19, 1883. (No model.) Patented in Germany September 15, 1882, No. '766.

| leads from the'chamber b upward through the tTo all whom 'it may concern Be it known that I, WILHELM NUssBEoK, a subject of the Kingdom of Prussia, German Empire, residing at the city of Berlin, Prus sia, have invented a new and useful Beer- Oopling Apparatus, (for which to obtain Letters Patent I made applica-tion to the German Government under No. 776 and date of September 14C, 1882,) of which the following is a specification.

My apparatus for cooling beer in casks has l for its object to cool the beer i`n the most dil rect manner, and at the saine time to cool the atmospheric air which enters the cask.

In the accompanying drawings, which illustrate the invention, Figure 1 is a vertical section of a beercooler, showing its application `to a eask. Figf2 is a vertical cross-section,

Fig. 3 an elevation, and Fig. 4 a horizontal section, ofthe upper part ot' the apparatus.

The apparatus consists principally of the cooling-pipe Aand the icereseivoir B. `The ice-reservoirfB is composed of an exterior and an interior casing,'both made ot' any suitable material, and the empty space formed between the two casings is filled with a bad conductor of heatcoal-dust, ashes, &c. Into the top ot' this double casing is screwed air-tight the double coverf, which cover is also filled with a bad conductor of heat.

Connected with the bottom ofthe ice-reservoir is the cooling-pipe A, surrounded by the conical jacket g, which at the same time forms a plug for the cash. In the interior ot' the icereservoir is situated the air'pipe c, which may be bent or corrugated, leading upward along the walls of the reservoir. r[his pipe comm unicates with the atmospheric air at the bottom of the reservoir, and has its mouth immediately underneath the top et' the same, as shown in Fig. 1. Before entering the icereservoir the air is cooled in this pipe by means ot the ice which surrounds the latter.

Situated in the interior of the ice-reservoir is a second air-pipe, d, also having its mouth underneath the cover, and discharging the cooled air immediately underneath the plug g into the Cask, over the level of the beer, as shown in Fig. l, through the opening d. A `third pipe, c, being a discharge-pipe for the water,

interior of the ice-reservoir B and discharges the waste cooling-water in proportion to the melting of the ice through cock h.

The cooling-pipe A is a metal pipe bent at a right angle and forming at its lower end the space b by means of the sieve. Upward from the space b and inside the pipe A leads the' water-discharge pipe c.

The sieve s is for the purpose ot1 preventing impurities from ice-water entering the pipe c. The cooling-pipe A is closed at its bent end with a cap, which may be removed when the apparatus is cleaned.

l? is the beer-cock.

The whole apparatus is constructed and made in such dimensions as to be easily handledthat is to say, iilled, emptied, and cleaned. When the apparatus is removed the cock L should be turned ot to protect the person who handles the saine from becoming wet. The jacketgis surrounded with an india-rubber ring for the purpose ot' bermetically closing the bung-hole.

What I claim is- 1. A beer-cooling apparatus comprising in its construction an ice-reservoir, a cooling-pipe leading from the reservoir into the cask and nearly to the bottom ofthe latter, and an airpassage leading atmospheric air into an icereservoir and delivering it into the air-space of the cask, substantially as described.

2."I`he combination of an ice-reservoir, B, with a cooling-pipe, A, an outlet-pipe, c, for waste water, an air-inlet pipe, e, and an airoutlet pipe, d, substantially as and for the purposes described.

3. The combination of ice-reservoir B, provided with a cover, cooling-pipe A, waterchamber b, provided with a sieve, waste-water 9o pipe c, provided with a tap, air-inlet pipe e, airt
